Betreff:    Re: [TYPO3-dev] Problem with changing query	according	to 
post-parameter

Hello Walter,

 > thank you for your answer. The thing you mentioned with changing the 
php style is absolutely correct. Much better to read. But when I changed 
to your example, I get an Illegal offset type in spl object.

Ok, I didn't test it, and I didn't use the construct with $valid(), 
$next() and current() before. The  Illegal offset type in spl object 
will disappear after my next hint.

ok, find the classname under which the class with the function 
printAsText() is intantiated inside the $view-class and then call the 
function printAsText() inside the discussed loop like this:

$content.= $CLASSNAME->printAsText( $this->current() );

'CLASSNAME' has to be replaced against the real Instance-Name.
If you can't find the function printAsText() you have to write one.

Best Regards
